These exercises are pointless, but I like doing them anyways. I'd bring in Iwakuma and then try to find some cheap starting depth to use as a long man. There are a lot of options like Blanton and Cahill, but we can wait for the market to develop.
I'd consider dealing Revere in a deal for a controllable relief arm like Cam Bedrosian, Brandon Maurer, or Zach McAllister. That would clear some payroll room to add depth in a number of areas and possibly another middle relief arm. I'd first look at Lowe and also consider Morrow, Broxton, or Madson on a one year deal.
